v Specification forming part of Letters Patent No. 173,151, datedFebruary 8, 1876; application filed January 3, 1876.

To alt/whom it may concern:

l Beit known that I, J OHNALLEN, of Lanesborough, Berkshire' county,Massachusetts, have invented an Improved Combined Toe- Calk Sharpenerand Die, of Which the following is a specification:

My invention consists of a die for forming' thecalk,and a beveledsurface provided with a cla-mp for sharpening the calk, combined with anupright that seats the diean'd sharp ching-anvil; and affords a bearingfor the clamp-lever, and, while enabling all ot' the 0perating parts tobe arranged in smallcompass,

' b in a vertical line below the surface C, and is prolonged through thestandard D to form a lever end, E, which is shaped' to present a treadlefor the pressure of the foot to operate the clamp, a spring, F,returning the lever end E when the foot is removed from the` treadlc toopen the jaw B and release the shoe from the clamp, as well as to leavethe clamp open for the 'easy reception of a shoe.

The clamp-surface c, adjacent tothe beveled surface C, is made narrowAenough to enable -the shoe to be turned by the pinchers, to have theangle of the inner face of the calk varied thejaws B and c.

The die .G and beveled surface G, aswell as `the axis b, are formed uponthe metallic portion H, which is fitted upon and bolted to the istandard D, so as4 to be thoroughly secured thereto, and so that allot'thestrain conse- A quent upon the blows is transmitted'to the standard,which may be secured upon a base,

as shown in the drawing, so that the machine may be portable, or may bepermanently secured in the desired position in the door of the shop.

The die G is'made of the length ofthe largest calk, so that' thescalemay find egress at the open ends, and it is so arranged that the edgect' one side forms an edge, a, of the inclined surface U, (this is shownin proilein Fig. L)

so that a bad edge can be cut oli" from the calk Without the necessityof' removing the shoe from the machine.

By this construction I am able to get a per-l fect die and Sharpener inthe smallest compass, and so that they mutually assist each other andrest upon a solid bearing.

Now, having described my invention, what I claim is In combination withthe standard D, having the spring F and clamp B, with its lever endE,the beveled surface C and die Gr, with intermediate edge a, in themanner and for the purpose set forth.

JOHN ALLEN.
